"Take home" technical test was the first stage, which was a warning sign. The test itself was poorly worded and ambiguous, but had a go anyway assuming that the outcome wasn't necessarily the aim. Test advised "no more than 1.5-2 hours" to be spend creating a solution that *required* unit tests and generally a level of detail that you wouldn't dare fit into, basically, a morning - start to finish - including being introduced to it. Feedback was excessively fussy, suggesting that they wanted a fully-fledged and tested solution to be produced in less than 2 hours. Dread to think what velocity they expect in the job. Overall rather an insulting process that I firmly regret undertaking, as I won't get those 2 hours back and I was made to feel like I should be grateful they even looked at it. If you search for "Maersk" on github, you'll probably find examples, as they demand you submit to a public repo with regular commits etc. Most examples on there are absolutely shocking, so they seem to have their work cut out for them. Interview difficult is based on the inhuman level of work required, rather than the task itself.
